REGNELL REGULATING DEVICE APPLIED TO FLUSH VALVESFiled March 22, 1955 Patented Aug. 6, 1940 REGULATING DEVICE APPLiED ToFLUSH VALVE l f Yngve Regnell, Stockholm, Sweden y y Application March22, 1935', seri'aifv @10511468 Inl Sweden March '7,193'37- 2 Claims.(C12. isi-93')l 'Y kThis invention relates to a device for regulatingthewater or fluid flow in flush valves or in apparatus of similarnature. In order to regulate or change the water flow, which is wantedto pass through the flush valve is generally has been necessarytofremove the cap or other parts of the ush Valve to be able to make thenecessary changes on the regulating part or partsof the apparatus. 1

The object of the invention is'to provideade- Vice whereby the water orfluid flow'through flush valves or similar apparatus can be regulatedfrom the outside of the apparatus. The object is obtained by a device,which makes it possible to change from the outside the reciprocableposition of the regulating parts in the apparatus, so that the water orfluid flow, leaving the apparatus, can be regulated to desired measurewithout dismounting or removing any parts of the apparatus whatever.

In the accompanying drawing Fig. l shows a sectio-n of a flush valvewith the regulating device connected to the push lever, Fig. 2 and Fig.3 are sections showing various constructions of the regulating deviceconnected to the push lever.

In Fig. l is shown the valve casing I and a diaphragm 2, which istightly pressed to the valve casing by the cover 3. The valve body 4 isby a lock device 5 securely fastened to the diaphragm 2. In the valvebody 4 is a channel 6,

through which the chambers above and below the diaphragm 2 communicate.Below the valve body 4 Aand connected thereto is a guided part 'l of themain valve, which keeps in place a gasket 8 of rubber or the like, whichtightens against a seat 9. In the valve body 4 is placed an auxiliaryvalve I0, which tightens against a seat II. On the stem I2, is placed asocketed member I3, which can slide on the stem. The member I3 isprevented from falling down by a shoulder I4 on the stem I2. The memberI3 can be operated by a push lever I5, which is slidably tted in a.casing I6, inset in the valve casing I in such a way, that the pushlever I5 itself or together with the casing I6 can be moved in diiTerentpositions and be locked in desired position by means of a screw I1 and agroove`2 I By unlocking the screw I1 and turning the casing I6,connected with the push lever I5 an eccentric disk IB will givedifferent connection spaces to the socket I3 and thus regulate the waterflow by operating on the inside regulating parts of the apparatus. Onthe inner end of the push lever I5 is attached the eccentric disk I8.Even so the casing I6 or other parts, Lthat guide the `push lever,can'beeccentrically `formed. n The push lever I5 is kept t'o its outsideposition through' a spring 4I9 and is prevented fromgturn-g ingyaroun'din the casing( I6 by a'pin 20.

2 is4 shown another design, where the push lever 2I isfarr'anged Iin acasing22 with a ball-'formed shoulder, whichV by an yoverlap 23 istightened againstthe valve casing I. By loosening thebo'lts 24`the pushlever can be `turned in different axial positions andiafterwards lockedinjthe desired `position by tightening the bolts.

" Inthe design shownr in Fig. 3 `tl'ieadjustment of the push lever isobtained by loosening `the mi bolts 26 and pushingthe casing IB, movablein the spare spaces 21 and 2'Ia upwards or downwards, whereby differentconnection spaces and the desired water flow regulation are obtained.

When the water passes into the valve through the inlet 25, the chamberbelow the diaphragm 2 is filled with water and through the channel 6 isthe chamber above the diaphragm lled with water. As the pressure area onthe top side of the diaphragm is larger than the area on the underside,the valve is kept closed by means of the water pressure. By pushing inthe push lever I5, the eccentric disk I8 operates on the socket I3appplied on the auxiliary valve stem I2, so that the auxiliary valve IIJis tilted to open position, whereupon a part of the water from thechamber above the diaphragm 2 runs away. The

. valve body 4 is now lifted by the higher pressure on the under side ofthe diaphragm, and the water is allowed to flow through the valve. Whenthe valve body 4 is lifted, will at the same time the auxiliary valve Iand stem I2 together with the member I3 be lifted. When the main valve 1is lifted to such a position, that the lowest edge of the member I3'haspassed the eccentric disk I8, the auxiliary valve I0 returns toitsoriginal position. The chamber above the diaphragm rells graduallythrough the channel 6 and the main Valve will be closed by the regainedpressure on the top of the diaphragm. If the push lever I is held in itsinward position the member I3 will abut the eccentric disky I8 and thestem I2 will slide down, by which arrangement the auxiliary valve I0will be kept closed.

The longer time the auxiliary valve will be kept open by the push leversoperating on the auxiliary valve, the more water will be allowed to passout of the chamber above the diaphragm, and the longer time it will takebefore this chamber will be refilled and the main Valve again will beclosed. Naturally the auxiliary valve must be opened to such a degree,that a larger amount of water will be allowed to ilow out therethroughthan into the chamber above the diaphragm through the channel 6.

By turning the casing I6 and operating the push lever, dierent parts ofthe eccentric disk I8 will be brought in contact with the socket I3, bywhich the valve body 4 must be kept open a longer or shorter time,before the auxiliarylvalve closes. This time can be varied between thelimits, which are controlled by the eccentricity of the disk I8 in sucha manner, that if the extreme part of the eccentric disk I8 touches thesocket I3, the time for the Water flow will bea maximum, and if thelowest part of the same disk touches the socket, the water flow Will bea minimum. By turning the-casingIS in different intermediate positionsthe Water ow can-be adjusted at will. The same result will be obftained, if the push lever is eccentrically located in the casing I6. Thesame result is obtained by various modications as shown in Fig. 2 andFig. 3, the means of regulating beingas described above. By using aregulating device according to this invention, the water flow in ilushvalves can be regulated from the outside in ,shortest possible time byusing a screw-driver.

Another advantage is that, if the Wanted water flo-w is not obtainedbythe rst regulation a smaller adjustment can immediately be done.

The invention claimed is:

1. A valve device comprising two valves, oneva main valve, whichcontrols the water flow, the

other an auxiliary valve for controlling the main valve, a dependinglaterally movable stem for controlling said auxiliary valve, a casingenclosing said valves and stem, a push rod mounted in a tubular guidingmember extending into said casing for engaging said stem so as to moveit laterally to open the auxiliary valve, and means for attaching saidtubular member to the casing so that it can be angularly adjusted,whereby the push rod contacts the auxiliary valve stem at differentdistances from the end thereof.

2. A valve device comprising two Valves, one a main Valve which controlsthe water flow, the

other an auxiliary valve for controlling the main valve, a dependinglaterally movable stem for controlling said auxiliary valve, a casingenclosing said valves and-stem, a push rod mounted in a tubular guidingmember extending into said casinlg so that the inner end of said pushrod is adjacent the end of said stem and may be moved into contacttherewith for actuating said auxiliary valve, said tubular member, whereit passes through the casing, having a spherical surface formed thereon,said casing having a corresponding surface, whereby the tubular memberand push rod may be angularly adjusted with relation to the auxiliaryvalve stem, thereby varying the time of closing of the auxiliary valveas the push rod contacts the stem at diierent distances from the endthereof, and means for retaining said 3Q tubular member in adjustedposition.
